TRANSOM-LOCK.

. SPECIFICATION-forming part of Letters Patent No. 739,300," datedSeptember 22, 1903.

I Application filed eptemher 11, 1902. Serial No. 122,953. (No model.) Il x invented certain new and useful Improvements in Transom-Locks; and Ido hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings,making apart of this specification, and to the figures of referencemarked thereon, in which- Figure l is aview showing a portion of thetransom and the same properly locked. Fig. 2

is a similarview, except that the transom is unlooked and in conditionto be swung upon its hinges. Fig. 3 is a transverse section show ing atransom locked. Fig. 4 is a transverse section showing the transomunlocked and partially swung upon its hinges. Fig. 5 is a detached viewof the lock-plate.

The present invention has relation to transoul-locks; and it consistsinthe different parts and combinations of parts hereinafter described,and particularly pointed out in the claim.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawin gs. c v

In the accompanying drawings, 1 represents the transom-rail to which thelook istobe at tached. I

The lock proper consists of the plate 2, fixed in any convenient andwell-known manner to the transom rail 1, to which plate is pivotallyconnected the lock-lever 3, which may be done by a rivet-or a screw, asdesired, as the only object is to pivotally connect the lock-lever 3 tothe plate 2 for the purpose hereinafter described. The lock-plate 43 issecured to the transom-sill 5, or it maybe attached at any other desiredpoint-as, for instance, if the transom is to swing from one of its endsthen of course the lock plate5 should be attached to the side casing.The

lock-plate consists of an angled piece of metal, as illustrated in Figs.3 and 4, and ,is so located that when the transom proper is brought intoa normal or closed position the shown in Fig. 1.

bottom or lower end of the lock-lever 3 will engage the vertical portionof the lock-plate 4:, as illustrated in Figs. 1 and 3. It will beunderstood that when the transom is closed or turned in the act ofclosing the transom the lock-lever 3 should be turned into thepositionillustrated'in Fig. 2, so that the bottom or lower end of the lock-lever3 will clear the vertical portion of the lock-plate 5, after which thelock-lever is turned upon its pivotal point and brought into theposition I For the purpose of allowing the bottom or lower end of thelock-lever 3 to clear the lock -plate 4 without turning the locklevertoany great distance beyond a vertical position the bottom orlower endof said lever is curved at an angle to its pivotal point. Forthe purposeof holding the lock-lever after it has been turned so'as to clear thevertical portion of the lock-lever 4 the stop-pin 5 is provided'and isformed integral with the plate 2 if desired. For the purpose ofpreventing the lock-lever 3 from accidentally turning upon its pivotalpoint when the transom is locked the stop-pin 6 is provided, whichstop-pin is located at a point where it will properly hold thelock-lever so as to securely lock the transom It will beunderstood thatby my peculiararrangement I am enabled to holdthe lock-lever-in'properposition to clear the lock-plate. t

The stop-pins 5 and 6are so located upon plate 2 that the lock-lever 3will rest upon said stop -pins regardless of the position of the lever,either to lock or unlock the transom. The stop-pin 5" shouldbe solocated that it will stop the lock-lever 3 before the top or upper edgeof the curved portion of the lock-lever 3 strikes thev bottomlor underside of the stop-pin 6, this being desirable to prevent the breaking ofthe stop-pin '6 by sudden throw of the lock-lever.

Having fully described my invention, what I claim as new, and desire tosecure byLetters I Patent, is-

The combination of a swinging or pivoted transom, and a plate secured toone of the rails of the transom, a lock-lever provided with alaterally-curved portion at its bottom hereunto subscribed mynalne inthe presence or lower end, a lock-plate held in a fixed poof twoWitnesses. sition and adapted to engage the look-lever, r p q i andmeans for limiting the pivotal movement (MIA EDSICT 5 of the 1ockleve1',substantially as and for the Vitnesses:
